I have an Ecodan 11.2kW. I switched off my main consumer unit leaving just the dedicated supply for the Ecodan pump and control system running at 24W background idle, agreeing with previous posts. Must be the control system. Whatever the standby consumtion may be, all I know is that in its first full year it has produced absolutely stunning results - 3,600kWh of electricity consumption for the year compared to 21,000kWh worth of gas the previous year. I'm having trouble believing the figures but if real that's certainly one way to help solve the energy crisis!!!
